The Dodge Viper GTS-R Commemorative Edition ACR was a limited edition variant of the Fifth Generation Dodge Viper (VX I) that debuted for the 2017 model year. These special edition cars were created as a tribute to the twenty fifth anniversary of the model, as well as an homage to the GT2 Championship Edition. The GTS-R was fitted with the ACR package and features the same 8.4L V10 engine as offered in the standard Viper as well as the 6 speed manual transmission, and is painted in a distinct white paint scheme with twin blue racing stripes. Just 100 examples of the Commemorative Edition were made, and of those, 5 were converted to Nurburgring Editions, which pay tribute to a privateer lap of 7:01 on the Nurburgring.
